"South Korea is the perfect location for a movie of this magnitude because it features cutting-edge technology, beautiful landscapes and spectacular architecture," Marvel Studios president Kevin Feige said. "We would especially like to thank the Ministry of Culture, Sports and Tourism (MCST) for making it possible for 'Avengers: Age of Ultron' to come to Korea."

"We're very excited to have the production in Korea, and also expect this to serve as the footstep of many more opportunities yet to come," minister of Culture, Sports & Tourism of Republic of Korea, Yoo Jinryong added.

Marvel Studios have confirmed the production will also shoot in Aosta Valley, Italy, with additional locations to be announced.

Jackson as Nick Fury, along with newcomers Aaron Taylor-Johnson as Quicksilver, Elizabeth Olsen as Scarlet Witch and James Spader as Ultron.
